The Senkaku Islands — known as the Diaoyu Islands in China — are eight uninhabited islands and rocks administered by Japan in the East China Sea, approximately 170 kilometers northeast of Taiwan and 330 kilometers west of Okinawa. Japan claims sovereignty. China claims sovereignty. Taiwan also claims sovereignty, though Taiwanese governments have generally handled the claim with less assertiveness than Beijing. The islands have no permanent population and no inherent economic value beyond the fisheries and potential hydrocarbon resources in the surrounding waters. Their strategic value lies entirely in their position: they sit at the junction of Japan’s Ryukyu chain and Taiwan’s northern approaches, and whoever controls them controls observation and potentially military positions that are relevant to both the East China Sea competition and the Taiwan Strait contingency.
